How do I use two cameras on my Raspberry Pi?
When building a Raspberry Pi setup to leverage multiple cameras, you have two options:
- Simply use multiple USB web cams.
- Or use one Raspberry Pi camera module and at least one USB web camera.
How do I find my camera ID on OpenCV?
Accessing the webcam
- To access a computer’s webcam or camera device, you can simply call the open() function on a cv::VideoCapture object (OpenCV’s method of accessing your camera device), and pass 0 as the default camera ID number.
- You can put this code in the main() function of your main.
How to attach a Raspberry Pi camera module to the compute module?
To attach a standard Raspberry Pi Camera Module to the Compute Module IO board, a small adaptor board, called RPI-CAMERA, is available. It adapts the 22W FFC to the Pi 15W FFC. As an alternative, the Pi Zero camera cable can be used.
What kind of camera does the Compute Module use?
The Compute Module has two CSI-2 camera interfaces. CAM0 has two CSI-2 data lanes, whilst CAM1 has four data lanes. The Compute Module IO board exposes both of these interfaces. Note that the standard Raspberry Pi devices uses CAM1, but only exposes two lanes. Please note that the camera modules are not designed to be hot pluggable.
Where is the cam IO1 on a Raspberry Pi?
The CAM_IO1 (LED Line) was used on the camera v1 previously to drive the LED. It is not in use on Raspberry Pi Camera v2, according to Raspberry Pi engineers. The pinout of the camera connector (on both the Raspberry Pi Camera and our board) is:
Where is the camera on the Raspberry Pi 2?
Here we can see my Raspberry Pi 2, along with the Raspberry Pi camera module (sitting on top of the Pi 2) and my Logitech C920 webcam. The Raspberry Pi camera module is pointing towards my apartment door to monitor anyone that is entering and leaving, while the USB webcam is pointed towards the kitchen, observing any activity that may be going on:
